Eaton ND63D79FCU Transformer - K-Factor nonlinear
Part Number: ND63D79FCU
Quick Summary
ND63D79FCU transformer delivers high-capacity isolation for 3-phase drive applications in manufacturing. Engineers often struggle to match transformer ratings with variable harmonic loads, risking overheating and downtime. In practice, regional deployments rely on standards such as CE marking for Europe and UL/CSA for North America, along with robust enclosure ratings for harsh environments. This solution pairs a 63 kVA rating with drive isolation and K-Factor nonlinear behavior to support reliable automation power distribution. With flexible installation options and compatibility with 480 V systems used across modern facilities, it helps reduce spare parts and maintenance costs while boosting plant uptime and productivity.

Eaton Specification Sheet - ND63D79FCU
The K-Factor nonlinear design provides enhanced harmonic mitigation, reducing thermal stress on windings and improving overall system reliability for drive-heavy loads. This translates to fewer deratings, longer transformer life, and lower maintenance costs in automated production lines. Ventilated construction with an 115C rise rating enables sustained loading without excessive temperature rise, supporting continuous operation of motors, conveyors, and pumps in demanding environments. The 3-phase 480V delta to 480Y/277V secondary configuration simplifies plant wiring and ensures safe motor starting for common automation motors, enabling faster commissioning and fewer troubleshooting steps. With a 63 kVA rating, the unit can serve multiple motors or a single heavy drive load, reducing the need for parallel transformers and lowering total cost of ownership. Compatibility with Eaton drive isolation solutions and standard installation practices streamlines retrofit projects and new builds, while the 838 lb weight is manageable for robust mounting in dedicated electrical rooms.
